9)Imagine a ticket selling booth at a fair. People passing by are requested to purchase a ticket. A ticket is priced as Rs.2.50/.The booth keeps track of the number of people that have visited the booth, and of the total amount of money collected.
Model this ticketselling booth with a class called ticbooth including the following members :
Data Members :
1)number of people visited
2)total amount of money collected.
Member Functons:
1) To assign initial values(assign 0 to both data members )
2)To increment only people total in case ticket is not sold out.
3)To increment people total as well as amount total if a ticket is sold out.
4)To display the two totals
5)To display the number of tickets sold out(a tricky one)
10) Write a C # program to perform various operations on a string class without using without using lanugae supported built in string functions. The operations on a class are:

c)Reverse the stirng d)Copy the string into an empty string
e)Concatenate two strings.
11)A book shop maintains the inventory of books that are being sold at the shop. The list includes details such as author, title , price,publisher and stock position.Whenever a customer want a book, the sales person inputs the title and author and the system searches the list and displays whether it is available or not. If it is not, an appropriate message is displayed.If it is then the system displays the book details and requests for the number of copies required. If the requested copies are available, the total cost of the required copies is displayed, otherwise the message “Sorrry”! These many copies are not in stock” is displayed.
Design a system using a class called stock with suitable member functions and constructors.
12)Imagine a publishing company that markets both books and audio-cassette versions of its works. Create a class publication that stores the title and price of a publication.From this class derive two classes : BOOK which adds a page count and TAPE which adds a playing time in minutes. Each of these three classes should have a getdata() functions to get its data from the user at the keyboard and a putdata() function to display its data. Write a main() program to test the book and tape classes by creating instances of them, asking the user to fill in their data with getdata() and then displaying the data with putdata().
3)Write a C sharp to read and display information about employees and managers.EMPLOYEE is a class that contains employee number, name, address and department. Manager class contains all information of the employee class and a list of employees working under a manger.
